Python – seaborn.regplot() method

Last Updated : 23 Jan, 2023

Seaborn is a Python data visualization library based on matplotlib. It provides a high-level interface for drawing attractive and informative statistical graphics. Seaborn helps resolve the two major problems faced by Matplotlib; the problems are ?

Default Matplotlib parameters
Working with data frames

As Seaborn compliments and extends Matplotlib, the learning curve is quite gradual. If you know Matplotlib, you are already half-way through Seaborn.

seaborn.regplot() :

This method is used to plot data and a linear regression model fit. There are a number of mutually exclusive options for estimating the regression model. For more information click here.

Syntax : seaborn.regplot( x, y, data=None, x_estimator=None, x_bins=None, x_ci=’ci’, scatter=True, fit_reg=True, ci=95, n_boot=1000, units=None, order=1, logistic=False, lowess=False, robust=False, logx=False, x_partial=None, y_partial=None, truncate=False, dropna=True, x_jitter=None, y_jitter=None, label=None, color=None, marker=’o’, scatter_kws=None, line_kws=None, ax=None)

Parameters: The description of some main parameters are given below:

x, y: These are Input variables. If strings, these should correspond with column names in “data”. When pandas objects are used, axes will be labeled with the series name.
data: This is dataframe where each column is a variable and each row is an observation.
lowess: (optional) This parameter take boolean value. If “True”, use “statsmodels” to estimate a nonparametric lowess model (locally weighted linear regression).
color: (optional) Color to apply to all plot elements.
marker: (optional) Marker to use for the scatterplot glyphs.

Return: The Axes object containing the plot.

Below is the implementation of above method:

Example 1:

Python3

# importing required packages
import seaborn as sns
import matplotlib.pyplot as plt
 
# loading dataset
data = sns.load_dataset("mpg")
 
# draw regplot
sns.regplot(x = "mpg", 
            y = "acceleration", 
            data = data)
 
# show the plot
plt.show()

Output :

Example 2:

Python3

# importing required packages
import seaborn as sns
import matplotlib.pyplot as plt
 
# loading dataset
data = sns.load_dataset("titanic")
 
# draw regplot
sns.regplot(x = "age",
            y = "fare",
            data = data,
            dropna = True)
# show the plot
plt.show()
 
# This code is contributed 
# by Deepanshu Rustagi.

Output :

Example 3:

Python3

# importing required packages
import seaborn as sns
import matplotlib.pyplot as plt
 
# loading dataset
data = sns.load_dataset("exercise")
 
# draw regplot
sns.regplot(x = "id",
            y = "pulse", 
            data = data)
 
# show the plot
plt.show()
 
# This code is contributed 
# by Deepanshu Rustagi.

Output :

Example 4 :

Python3

# importing required packages
import seaborn as sns
import matplotlib.pyplot as plt
 
# loading dataset
data = sns.load_dataset("attention")
 
# draw regplot
sns.regplot(x = "solutions",
            y = "score",
            data = data)
 
# show there plot
plt.show()
 
# This code is contributed 
# by Deepanshu Rustagi.
